Applications of the ARGUS code in accelerator physics

Abstract

ARGUS is a three‐dimensional, electromagnetic, particle‐in‐cell (PIC) simulation code that is being distributed to U.S. accelerator laboratories in collaboration between Science Applications International Corporation (SAICTM) and the Los Alamos Accelerator Code Group (LAACG). It uses a modular architecture that allows multiple physics modules to share common utilities for grid and structure input, memory management, disk I/O, and diagnostics. Physics modules are in place for electrostatic and electromagnetic field solutions, frequency‐domain (eigenvalue) solutions, time‐dependent PIC, and steady‐state PIC simulations. All of the modules are implemented with a domain‐decomposition architecture that allows large problems to be broken up into pieces that fit in core and that facilitates the adaptation of ARGUS for parallel processing. ARGUS operates on either Cray or workstation platforms, and a MOTIF‐based user interface is available for X‐windows terminals. Applications of ARGUS in accelerator physics and design are described in this paper.
